Parameters

quota_root should normally be in the form of
user.name where name is the mailbox you wish to
retrieve information about.

Return Values

Returns an array with integer values limit and usage for the given
mailbox. The value of limit represents the total amount of space
allowed for this mailbox. The usage value represents the mailboxes
current level of capacity. Will return FALSE in the case of failure.

As of PHP 4.3, the function more properly reflects the
functionality as dictated by the » RFC2087.
The array return value has changed to support an unlimited number of returned
resources (i.e. messages, or sub-folders) with each named resource receiving
an individual array key. Each key value then contains an another array with
the usage and limit values within it.

For backwards compatibility reasons, the original access methods are
still available for use, although it is suggested to update.

If you're using this (or probably any other imap functions) and getting "Notice: Unknown: Quota root does not exist (errflg=2) in Unknown on line 0" errors after the script finishes, then call imap_errors() function before you close the imap stream - this will clear the error stack and you don't get those annoying notices.
